Hi Dave, everyone...

Hi all,
I'm having a lot of trouble using renderString from Graphics.UI.GLUT.Fonts.
All my attempts to render a StrokeFont have so far failed.
Using a BitmapFont I can get strings to appear but they demonstrate
the odd behaviour of translating themselves a distance equal to their
length every time my displayCallback function is evaluated.
My requests are:
* Does anyone know how to keep the position fixed?
One way is to wrap the drawing action with preservingMatrix :
http://cvs.haskell.org/Hugs/pages/libraries/OpenGL/Graphics-Rendering-OpenGL-GL-CoordTrans.html#v%3ApreservingMatrix
(re-exported from the main GLUT module, if I read the docs correctly)
This pushes the transformation state to a stack, executes the action,
and restores the transformation state from the stack.
More useful when you have complex scenes/subscenes/subsubscenes etc, but
should work here too.
